The evaluation board EVAL-FFXMR20KM1HDR allows the customer to begin initial characterization
measurements very quickly. Due to the usage of the EiceDRIVER™ 1ED38x0Mc12M and its flexible parameter
setting options via I2C-BUS the EVAL-FFXMR20KM1HDR can be quickly adapted to different applications (like
DC/DC-converter, Solar applications, UPS systems, Solid state transformer, Drives and others) without
changing the hardware. This flexible parameter settings are provided by 27 configuration registers accessible
via I2C. These configuration options influence many threshold and timing paramaters to optimize the circuit for
its intended application. In addition to the flexible parameter setting options via I2C-BUS, the EiceDRIVER™
1ED38x0Mc12M contains 16 status registers. These can also be read out via the I2C-BUS and can therefore
provide information about various states of the driver stage. This is the so-called condition monitoring and can
serve as enabler, if wanted, for predictive maintenance. For more information we refer to the EiceDRIVER™
1ED38x0Mc12M reference manual here.
Without the need to modify external components during evaluation, the whole process becomes much faster
than before and enables, what we call, rapid-prototyping.
Another important feature of the EiceDRIVER™ 1ED38x0Mc12M is the soft-off behavior in the event of an worst
case error, the short circuit. The driver has an integratet DESAT module which switches off the driver in a short
circuit event. Due to the high currents that occur in these event and a simultaneous hard switch-off, very high
peak voltages can occur due to parasitic inductances. These can reduce the life-time of the power switch or can
destroy the whole application. With soft-off behavior, only a part of the maximum gate current is used for
switch-off. As a result, the power switch turns off more slowly and the peak voltage can be limited significantly.
Both the soft-off behavior and the permitted current levels (within certain limits) can be set via a configuration
register.
